It seems obvious that, other than allowing the quarry to 'bleed out', arrows, even modern ones, have limited if any use, consistent that is with humane hunting.
Would anyone use a 30-06 for dangerous game ?
To be humane, without 'gambling', it seems logical to use a rifle and a big one at that, most BG rifles are intended to be used at very close range.
A modern broadhead is about 100 grains (7000 grains to the lb). The arrow shaft is the rest.
Anything dying from blood loss alone, may take a very long time to die, as here.
Humane?
Not in my book. My last comment on this.
